Time is a skill.
Precision timing reps measured in milliseconds against a click - subdivision, matching and drift.
Timing
Landing exactly on the beat
A click plays at tempo - tap on every beat and see how close you land, in milliseconds. One rep is one timed run, starting at 70 BPM with a generous window, working up to 160 BPM tight.
Subdivision
Feeling even subdivisions between the beat
A steady click marks the beat - tap the subdivisions in between from your own internal grid. One rep is one timed run, starting at eighth notes, working up to sixteenths at faster tempos.

Holding the beat when the click drops out
Tap every beat while the metronome clicks less and less often - every beat, then every 2 beats, every bar, up to every 4 bars - at the same tempo. One rep is one tap, measured in milliseconds against the true beat.
